Title: Power source control system for switching type power source
Inventor: TAKAHASHI MAMORU
IPC: H02M3/335
Filed: 1982-09-29
Abstract: PURPOSE:To effectively prevent the abnormal rise of an output power source voltage when the circuit becomes abnormal by controlling the transistor current of a photocoupler in response to the output power source voltage. CONSTITUTION:When a switch S is closed so that a transistor Q1 becomes ON, a condenser C4 starts charging by a coil N5. A transistor Q3 is turned ON at this time point, the transistor current of a photocoupler PC increases, and the transistor Q2 is not turned ON until the current flowed to the resistor R3 becomes considerably large. Accordingly, the conversion energy through the transformer T is large. Thereafter, when the output gradually increases, the current of the transistor Q3 decreases, the transistor current of the photocoupler PC thus decreases, thereby early turning the transistor Q2 ON and reducing the switching power.

Title: Electromagnetic hydraulic damper
Inventor: KASHIMA MITSUHIRO
IPC: F16F9/46
Filed: 1989-07-03
Abstract: PURPOSE:To prevent the generation of poor operation by wear iron powders by using a valve body of non-magnetic material crossing an operating oil passage to change the passage cross sectional area, an adsorption part of magnetic material displaced integrally with this valve, and a solenoid sucking the adsorption part by an electromagnetic sucking force according to exciting current to constitute a solenoid valve. CONSTITUTION:When a solenoid 21 is excited, a magnetic field connecting magnetic materials around this is formed, and an absorption part 23 is adsorbed by a stopper 22. A spool 24 (non-magnetic material) integrated with the adsorption part 23 is displaced upward to interrupt the communication between an operating part 24A and a port 30. Under the state where the solenoid 21 is not excited, the opening part 24A is largely superposed with the port 30. When ON and OFF of the exciting current of the solenoid 21 is periodically repeated, the communication and interruption between the opening part 24A and the port 30 is repeated, and the generating attenuating force is set according to duty ratio. As the spool 24 is made of aluminium alloy and has a small mass, it is displaced with satisfactory responsibility, and never adsorb wear iron powders in operating oil.
